javadoc problem with default-jdk

[Picca Frédéric-Emmanuel <frederic-emmanuel.picca@synchrotron-soleil.Fr>]

hello as I am working on my remotetea package, I build it using the
pbuilder.

and it seems that depending on default-jdk is not enought to produce
good documentation with javadoc. Indeed it do not find the
documentation for standard classes of java.

what must I add as build dependency to produce the right documentation ?

thanks

Frederic
